HENRY D. SCHMIDT, vOF NEW YORK, N. Y.

EMBOfiSING-MACHINE.

Application filed June 10, 1916.

T 0 all whom it may concern:

Be it known that I, HENRY D. SCHMIDT, a subject of the Emperor of Germany, residing at Astoria, in the borough of Queens, city of New York, county of Queens, and State of New York, have invented certain new and u'eful Improvements in Embossing- Machines, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to embossing machines and more particularly to a machine of this typeadapted for use in finishing textiles or similar products.

Heretofore, in machines of this type the pressure between the pattern roller and its opposed platen roller has been developed by the application of pressure to the arbors of the pattern roller. This practice results in the springing of the pattern roller toward the center thereof in a manner to cause unequal pressure along the line of engagement of the pattern and platen rollers with a resultant variance in the height of the embossed portions of the teX tile at different points thereof. In this type of machine it is necessary to use a heated pattern roller and upon the completion of the run of the machine it isnecessary to separate the pattern and platen rollers to avoid burning of the facing upon the latter. In machines heretofore used, this separation has been secured by moving the pattern roller away from the platen roller by means of set screws operative at opposite ends of said platen roller, which. set screws are used to develop the pressure between the rollers, thus necessitating are-adjustment of the pressure when re-setting the machine for a subsequent run.

A machine made in accordance with my invention is so constructed that the stresses developing pressure between the pattern and the platen rollers will be applied to the former by the latter along substantially the entire length thereof so as to minimize a tendency of the pattern roller to spring away from the platen roller, a counter stress being applied along a limited portion of the pattern roller adjacent the center thereof at all times while the machine is operating so as to correct any slight distortion of the pat-- Specification of Letters amt;

tern roller adjacent the center. Vhile the means developing the pressure stresses and the means developing the counter-stresses operate simultaneously upon the pattern roller, each is provided with its own operating and adjusting mechanism so that the relative pressures upon the opposite sides of the platen roller may be regulated to meet different conditions of use in the machine.

The machine 1S also so constructed that while it may be set for a certain pressure, the

.theless, this pressure may be varied independently of said last named mechanism. The counter-pressure roller is also provided with a throw-off mechanism operative inde pendently of the throw-off mechanism of the platen roller, by means of which said counter-pressure roller may be rapidly moved into and out of engagement with the pattern roller without disturbing the adjustment for pressure, said throw-off mechanism operative upon said counter-pressure roller being capable of developing variable pressure through said roller independently of the mechanism by'means of which the machine may be set fora definite pressure as to said roller.

The platen roller, pressure roller and counter-pressure roller are preferably all driven at the same peripheral speed, each of said rollers being removably mounted in the machine in a manner to permit the removal of the several rollers and the substitution therefor of other rollers bearing different designs and having different dimensions.

I also provide a special heating attachment for the pattern roller which will have the effect of distributing the heat alon substantially the entire length of the roler in a manner to secure uniform heat cmiditions throughout the roller and avoid the necessity for constant attention to the heating attachment and frequent movement thereof to avoid over or under heating of the roller in spots. I also provide a pressure developing mechanism which will insure an absolutely parallel movement of the platen roller, thus I facilitating the rapid setting of the machine forthe desired pressure and permitting frequent re-adjustment of the machine without likelihood of a loss in the alinemcnt ofthe platen roller.

The invention consists primarily in an embossing machine embodying therein the novel features of construction and combination of parts hereinafter set forth and described and more particularly pointed out in the claims hereto appended.

. ports for the platen or pressure roller; and

Fig. 5 is a detail view of a part of the throw-off mechanism for the counter-pressure roller.

Like letters refer 'to like parts throughout the several views.

In the embodiment of my invention shown in the drawings, the pattern roller carrying the engraved embossing plateis shown at 10,

, .the arbors of said roller being mounted in suitable saddles and stirrups, indicated at 11, to facilitate the mounting and removal of this roller. The roller 10 is mounted in fixed bearings, the pressure required in the operation of the machine being developed by the movement of the pressure or platen roller and the counter-pressure roller toward said roller 10. Mounted below the roller 10 is a platen or pressure roller 12 which is provided with the usual facing for the pur pose of permitting the desired impression to be made upon the cloth by the plate upon the roller 10. To permit the movement of the roller 12 toward and from the roller 10,

3 I mount the arbors of said roller in "ertically reciprocatory housings-13, said hous- ElllgS being actuated by means of oppositely 'dispo'sed feed screws 14 each of'which carworm shaft 16, provided with a ries a worm wheel 15, acted upon by the and wheel to the same extentimparted thereto, thus insuring an absolutely parallel movement of the said roller 12 and uniformity in the ap plication of pressure throughout the entire length of the said rollers 10-12. The uti- By this construction both arbors of the roller 12 may have "simultaneous movementlization of a worm shaft and worm wheels also permits nicety in the regulation of the pressures.

To permit the movement of the roller 12 toward and away from the roller 10, without disturbing the adjustment for pressure secured by'the mechanism above referred to, I makethe housings 13 in two sections and mount in'one of these sections, a cam shaft 18, the cams 19 upon which operate on the othersections in a manner to cause the raising or lowering of the section in which the arbors of the roller 12 are mounted. Mounted upon said cam shaft is a ratchet wheel 20 acted upon by a pawl 21 so as to permit the cams 19 to be set in any adjusted position, thus permitting a variance in the pressure for which the machine is set by the screws 14 by means of said cams. The shaft; 18 carries an operating handle 22. The pawl is controlled by the release mechanism 23. The said cam shaft 18 and its appurtenances constitute a throw-01f mechanism by means of which the rollers '1012.may be quickly separated when the machine is not operating, thus avoiding likelihood of'the burning of the facing upon the roller 12 through a continued contact with the heated. plate upon the'roller 10.

Power is applied to the machine through the gear train 24: acting upon the roller 12 and the gears 25 and 26 carried by thearbors of said roller 12 and the roller 10 respectively. At 27 I have shown a pulley carried by the main power shaft 28 of the machine. v

While the manner of advancing the roller 12 toward the roller 10 will minimize the tendency of the latter to spring out of true,

nevertheless, with the operation ofthe machine, that portion of said roller 10 remote from its arbors will yield from the resistance encountered as the cloth passes between the center thereof and the platen roller. To avoid this condition, I provide a short roller 29 through which a pressure counter to that developed by the roller 12 is applied toa short section of the 'roller 10 adjacent the center thereof only; By using ashort roller '29, or one the length of which-is considerably less than that of the roller 10, I localize the counter stresses, and restrict them to that portion of the roller 10 which is subject 7 to distortion, or loss of alinement. The

, roller 29 is mounted between-the arms 30 of a yoke,'said arms being pivotally mounted at 31 in the frame of the machine and said yoke being provided with a stem 32,- the said roller being mounted between the points of pivotal support 31 and the said stem so'that cause the exertion of the desired pressure upon the roller 10 by the roller 29. The roller 29 is provided with a face similar to that used upon the roller 12. One arbor of a downward pressure upon said stem will the roller 29 is connected by means of a universal oint 33 wlth a drivlng shaft 3%, the

gear 35 upon which shaft is in mesh with the gear 26 so as to impart positive rotary movement to said roller 29.

Carried upon standards 36 is a shaft 37 upon which the yoke 38 is pivotal'ly mounted. Said shaft carries at each end thereof cams 39 by means of which the yoke 38 may be raised or lowered. The shaft 37 centrally thereof is adapted to be engaged by the stem 32 so that when the said shaft is turned by means of the hand wheel 40, it and the yoke 38 will be raised and substantially simultaneously the stem-32 will be raised carrying with it the roller 29 so asto bring said roller out of engagement with the roller 10. The yoke 88 has mounted therein a hand screw 41 adapted to bear upon the ste1n32 in a manner to force the roller 29 into engagement with the roller 10 with the resultant development of the desired pressure to withstand. the distortion strains developed upon the roller-10.

The sha 't 37 and the cams 39 may be used pendently of and without disturbing, the

adjustment forpressure secured through the said screw 41.

The roller 10 is made of hollow metal, heat I being applied tot-he interior of the roller for the purpose of bringing the engraved embossing plate or cylinder carried by said roller, to the desired temperature. One end of the cylinder is open as shown in'Fig. ,1 to permit the insertion of an elongated burner tube 42 within said cylinder. Theouter end of this tube a2 is forked, one arm thereof, as

43 being connected to a gas pipe A and the other arms 45 being connected with the air pipe l6 or other means for delivering a medium to said tube in conjunction with the gas for the purpose of developing a combustible mixture which will develop heat of the desired intensity. Y

The burner tube 42 merely rests upon the bottom of the opening in the roller 10 so that said roller will turn freely without the necessity for supplying swiveling connections between the burner and the connections from which it receives its combustible mixture.

To secure the desired distribution of heat throughout the embossing plate upon the roller. the-tube 4 2 is made of substantially the same length as the said roller and is proyided with a plurality of small jet openings distributed along the length thereof.

To permit the quick separation of the arms from the gas. and air supply pipes l t- L6, the connections between said arms and said pipe consist of a flexible rubber tubing so that by disconnecting said tubing the burner in its entirety :may be withdrawn as it passes between the said rollers. If desired a spraying pipe 19 may be mounted below the rollers i8 so as to dampen the textile slightly before it passes between the said roller.

li founted upon pivotal arms 50 is a guard roller 51 adapted to bear upon the roller 12 to facilitate the threading of the textile through the machine while the machine is running without endangering the hand of the operator.

At the delivery end of the machine, 1 pro- I ride a roller 52 over which the cloth passes after leaving the rollers 1012, which roller is driven by means of the pulley 53 and belt 51 driven from the shaft of the intermediate gear of the. train 24.

Carried by the standards 55 at the delivery end of the machine are brackets 56 in which a weighted roller may be mounted for the purpose of permitting the cloth to be held taut between the roller 52 and the emboss ing rollers. Also carried by the standards 55 are brackets 5? adapted to receive a table upon which the cloth after being embossed may fall in folds.

The operation of the herein described machine is substantially as follows A pattern roller 10 having the desired design thereon, being mounted in the machine,

the saddle and stirrup for the arbors of said roller arefirmly connected so as to prevent vertical displacement of the said roller. The operating handle 22 is then pulled clownwardly so as to set the cams 19 with the high point thereof so positioned as to advance the platen roller 12 toward the roller 10. Thereafter the hand wheel 17 is used to turn the worm shaft 16, and the screws 1% through the worm wheels 15 carried thereby, thus simultaneouslyraising both housings 13 and moving the roller 12 in its entirety toward the roller 10. By applying power simultaneously to both housings 13 by the same actuating mechanism, the roller 12 will receive a parallel movement without likelihood of a loss of alinement or development of variable pressures at the opposite ends thereof. In this manner, the machine may be set for a lieved or varied without disturbing the adjustment secured by means of the screws 14 and their actuating mechanism.

Either before or after the setting of the machine for pressure by means of the screws 14, the shaft 37 is so turned by means of the handwheel 40 as to cause the cams 39 to bring the yoke 88 to itslowermost position.

- Thereafter the hand screw 41 is turned to 1 force the stem 32 of the yoke 30 downwardly adjacent the center of the roller 10-since a a short roller 29 has less tendency to spring than a long roller and pressure applied along the top of the roller 10 for a short distance upon opposite sides ofthe center thereof, will serve to effectively counteract a tendency of said roller to spring at any point intermediate the arbors thereof. I lay particular stress upon the use of a short roller 29 because in practice I havc found this constructionto be highly effective in preventing distortion of the pattern roller, and in fact,

an essential characteristic of the pressure developing mechanism in the machine.

Y means of the control of the fuel supply as cylinder, uniform distribution of the heat The hand screw 41 may be used to set the roller 29 for a certain pressure, whlch pressure may be relieved or varied by means of ithe cams 39 without disturblng the adpist- 'ment secured by means of the sald screw 41.

The machine having been set. in the manner described, the lever 22 is raised, the pawl 21 being released to perm t the rotation of the shaft 18 and its cams 19, so as to permit the roller 12 to drop out of engagement w1th the roller 10. At the same time the hand wheel 40 is turned so as to actuate the cams 39in a manner to raise the shaft 37 and the stem 32 and move the roller 29 away from the upper'radius of the roller'lO and-- out of operative engagement therewith;

'The burner 42 is then inserted in the roller 10 and power is applied to the machine until the said roller has been properly heated, the paper or .other facing of the roll ers 12 and 29 not being in engagement with the said roller 10 by reason of the actuation of the respective throw-out mechanisms by means of the lever 22 and wheel 40. The burner 42 remains in this position during the entire run of the machine, any modification of the heating effect being secured by distinguished from the physical movement of the burner ltselfp By using a burner having jet openings distributed along the entire length thereof, which length is sub-- stantially the same as that of the pattern 1 throughout the entire plate is secured.

hen the roller 10 is properly heated the lever 22 is used to raise the roller12 and the machine so as not to bring it into engagement with therolleflO, =developing that pressure for which the ma-- chine was previously set by means of the screws 14. At the same time the handwheel 40 is turned so as to draw the yoke 88 downwardly and force the roller 29 into engagement with a point diametrically opposite the line of engagement between the vrollers '10 and 12, developing that counter- .pressure for which the machine has been previously set by means of the handscrew41.

The end of'the cloth is then threaded over and about thetensioning and guide rollers 48 and beneath the guard roller 51, this guard roller initiating the feed of the cloth and, preventingthe hand of the operator being drawn between the platen and pattern rollers; As the cloth, is embossed and leaves the rollerslO and 12, it passes over the de livery roller 52 which is driven at substantially the same peripheral speed asthe rollers 10 and 12- so as to prevent the formation of slack between it and said rollers. A table to receive the cloth maybe mounted upon the brackets 57. If desired no such table need be used; and in this case the said brackets may be turned within the: frame of interfere with the workman. v

Byproviding rollers 12 and 29 with independently operative means by. which they ;may be set to develop the desired pressure, j' the pressure and counter-pressure to which the roller 10 is subjected may be so controlled as to secure the desired operative effect upon the roller 10 and the relative pressure exerted by said rollers 12 and 29' may be so proportioned as to avoid subjecting the roller 10 to excessive-pressures. So long as the machine isrunning, there is @no tendency'of the roller 10 to burn or'char *the facing upon the r0llers 12 and 29, but

up'on'the stoppage of the machine there is such a tendency, To permit the rapid sepaw ration of the; rollers 12 and 29 from the roller 10, vthe throw-off mechanisms here- "to-fore described are provided. These throwoif mechanisms when the machine is stopped should be immediately actuated and since the stoppage of the machine is frequent, it" is desir'ableto ,providesuch mechanisms as 7 may be operative to so separate the'rollers and restorethem to their operative'relation without the necessity for re-adjusting the pressure of the machine each time said roll.- ers are restored to the operative relation. In the machine heretofore described to move the roller 12 out of engagement with the roller 10, it is merely necessary to release the pawl'21 and raise the lever 22, the cam shaft 18 carrying said lever, simultaneously turning both cams 19 in a manner to-permit the section of the housings 13 in which the roller 10 is .mounted to drop to an extent sufficient to cause the roller 12 to move out:v

of engagement with the roller l0. Ihe roller 29 is moved out of engagement with the roller 10 by merely turning the hand wheela0, the cams 39 carried by the shaft 37 simultaneously raising said shaft, the yoke 38,- the screw 41 carried thereby and the stem 32 of the yoke 30 carrying said roller 29. It will be observed that the actuation of the cams 19 and 39 does not disturb the adjust-ment of the screws 14: or 41 so that a return of said cams to their former positions will bring the rollers 12 and 29 to their former positions where the screws 1a and il will determine the degree'of pressure of the rollers 12 and 29 upon the roller 10. By using cams as the actuating means for the throw-off mechanisms, the desired pressure may be developed and rapidityof movement of the rollers 12 and 29 is secured.

If it be found in the operationof the machine that the pressure for which the machine is set is too great,- this pressure maybe relieved by a slight movement of the cams 19 and 39 or when setting the machine for pressure by means of the screws 14: or 11 the cams may be so set that a pressure-may be exerted in excess of that for which-the screws 14 and 41' are set a slight movement of the cams in the direction opposite to that inwhich they are turned to throw their respective rollers out of engagement with the platen roller. I r

In a machine made in accordance with my invention adequate lubrication may besecured by means of bearing caps or oil cups, the design of the machine being such as'to lend itself to the use of this system of lubrication. Heretofore, in embossing machines, the question of lubrication has been a difiicultone. If desired a spraying tube may be used below the tension and guide rollers 48 to dampen the cloth before it'passes between the rollers 10 and 12. This is a common expedient in this art, however, and I lay no claim of invention thereto.

It is not my intention to limit the invention to the precise details of construction shown in the accompanying drawings, it being apparent that many of the refinements shown in the drawings may with, without departing from t-he'sp'irit and scope of the invention. I 'have found it essential to use a counter-pressure roller, length of which-is considerably less than that of the pattern this counter-pressure roller so that the stresses therefrom will be applied at and ad-- jacent the center of the said pattern roller and I intend to claim such broadly. I also believe it is broadly new to'provide an embossing machine wherein the pressure upon the pattern roller is developed by the movementof the platen roller toward said pattern roller. I also believe it to be new to provide a pressure regulating mechanism inbe dispensed the roller and to position eluding therein a throw-01f mechanism so that the pressure between the platen roller and the pattern roller may be entirely relieved without disturbing the adjustment for pressure and which may be actuated to substantially instantly restore this pressure.

Having described the invention what I claim as new and desire to have protected by Letters Patent is r 1.
